IMPROVEMENT IN GVERNORS FOR STEAM AND OTHER ENG-INERY.

The Schedule referred to in these Letters Patent and making part of the name.

'To all whom it cna/y concern Bc it known that I, BENJAMIN MAOKERLEY, of Paint, in the county of Highland, and State of Ohio, have invented a new and useful Improvement'in Atmospheric Governors; andI do hereby declare that the following isa full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l represents a sectional elevation of my improved governor, and

Figure 2 represents asection of one of the valvel tubes, taken on the line ex of g. 1.

Similar letters of reference indicate like parts.

The object of this invention4 is to provide a simple and effective atmospheric governor, for regulating the motion of prime movers, but adapted moreA especially to machines actuated by animal power. v

It consists of a cylinder-,having a piston actuated hy a crank, or other suitable means, connected to the machine or niotr for which it is to act as a governor; the cylinder being provided at each end with weighted valves, which govern -the ingress and egress of air' to the cylinder, and thereby the resistance of `the piston to the machine by the force of the blast on the valves.

A represents a cylinder, having a piston, B, which is designed to be connected to the 'machine or motor, the motion of which is to be regulated by a crank and connecting-rod, G, or by any other suitable means.

D represents valve-tubes at each end of the cylinder, having passages, E, openpto the atmosphere, which are provided with gates or slides, F, to vary the area of the same. There may be, if preferred, two of these openings for one valve, one opposite to the other, whereby the lateral pressure of the air on the valves will vbe balanced..

G represents Weighted tubular valves, arranged -to work vertically inthe tubes, having lateral passages,

H, corresponding to the passages E, and also slots, I, in the side, whereby their vertical movement is limited by the pins, K.

rIhe weight ofthe said valves is intended to be such that, when the machine is running at its required velocity, they will rest onthe pins K, when the passages H and E will' be coincident with each other, and the lleast resistance will be oii'ered to the passage of the air, but if the speed increases, the increased pressure of air under the valves will raise them, so as to contract the area of the passages, and thereby give greater resistance to the piston, which, in turn, resists theV motion of the machine or motor from Which it receives motion.

' movement of the valves causes a material-variation of the pressure.

'Of course, when the speed slacks, the valves will fall, and the passages open, and reduce the resistance.

'Thevalyes-maybe-provided with a balance-Weight,

if preferred. l L represents adjusting-screws in the upper ends of the tubes, for the puipose 'of regulating the upward movement of tl1e'-valves.

Having thus described' my invention,

I claim as new, and desire to secure by Letters Patent- V l. The combination, with the air-cylinder A and plunger B, -of the tubes D, having passages E and the Weighted valves' G, substantially as described. y

2. The tubes D, provided with the gates F, adinetablc plugs L, and pins K, substantially as described The above specification of my invention signed by me, this 24th day of July, 1868.
